“…The developments of wide-area measurement systems (WAMSs) [7,8] and robust non-linear schemes [9][10][11][12] have brought new opportunities to design the LCC HVDC emergency power control. A non-linear robust control law, such as feedback linearisation method, sliding mode control and backstepping control technique, has been used to design the LCC HVDC emergency power control strategy based on the global signals of the AC-DC parallel system measured by WAMS.…”

“…In the ELS control strategy, the virtual electronic-sha functions the same as the physical line sha in the traditional mechanical sha and can drive the other slave sha s by transmitting the control signal [21,23]. e control strategy of virtual line-sha ing lies in its feedback mechanism [20]. In this paper, the feedback characteristics of the control strategy of virtual line-sha ing are used.…”

This paper investigates a virtual line shafting-based total-amount coordinated control method of multi-motor traction power to solve the traffic safety problem caused by train traction power loss. This method considers the total amount instead of the synchronous control amongst single motors in a multi-motor control system. Firstly, a block diagram of the proposed method is built. Secondly, on the basis of this diagram, an accurate system model with parameter perturbations is constructed. Thirdly, a virtual controller is designed to quickly adjust the output torque of the virtual motor and to realise a tracking control of the reference torque. A total-amount coordinated control strategy based on the integral sliding mode is also designed to keep the total traction power of the multi-motor system constant under uncertain and unknown disturbances. Lyapunov stability theory is used to prove the system stability. The simulation and experiment results verify the effectiveness of the virtual controller and the total-amount coordinated control strategy in guaranteeing system robustness under disturbances and parameter perturbations.

“…At present, multiaxis servo synergic control structure [2,3] mainly includes master-slave type, virtual line-shaft type, cross-coupling type, relative coupling type, and ring coupling type. From the existing study results, the masterslave type is proposed in [4], whereas the virtual line-shaft type is adopted in [5]. Although these control structures are simple in design and easy to implement, the synchronization control performance is poor due to the failure of introducing signal feedback mechanism.…”

This paper investigates a relative coupling control strategy based on the sliding mode controller to solve the problem of poor synergy performance of the axes of the dynamic seat during operation and to realize the multiaxis servo synergic control with variable proportions during the operation of the system. Firstly, the proposed method is theoretically proven to be accurate in eliminating tracking errors and synchronization errors between servos in the process of system operation. Secondly, the system simulation model is built in the Simulink simulation environment of MATLAB. On one hand, the final simulation result verifies the accuracy of the theoretical proof. On the other hand, the control strategy is characterized by fast convergence, high synchronization accuracy, and strong robustness; thus, the system has excellent synergy performance. Finally, the motion control platform of the dynamic seat was built for physical verification. The experimental result shows the effectiveness and feasibility of the control strategy.
